(3)... (b) -(f)." Board staff and:the LEA measured methane gas levels at three multidepth probes (GP-9, GP-11 & GP-12), using the operator's LandTec GEM -500 instrument. We obtained methane gas readings of 0.00%in all depths of#GP=9, on monitoring probe#GP-12,we obtained methane gas readings ranging from 1.1 to 3.2%, and on GP-1 I,we obtained methane gas-readings of 13.2%in the Shallow Depth, 23.9%in the Medium Depth, and 0.00%in the Deep probe. The levels of methane gas obtained in the shallow and medium depths on landfill boundary monitoring probe#GP-11 constitute a violation relative to the requirement of the State Minimum Standard(SMS) indicated above. Area of Concern: 27 CCR Section 20921(b) -Gas Monitoring and Control On April 19,2007,the California Integrated Waste Management Board(CIWMB)revised its regulations governing landfill gas (LFG)monitoring and control for active disposal sites. The new regulations apply to active disposal sites the more detailed gas monitoring and control regulations previously applicable to only closed sites. The Office of Administrative Law (OAL) approved the regulations on August 21,2007. The regulations became effective on September 20,2007. The new regulations require operators of active landfills to submit LFG Program Plans(Plans)that demonstrate compliance with the LFG monitoring criteria to the Enforcement Agency(EA)and CIWMB for EA review and approval and CIWMB review and concurrence. The regulations required that active disposal sites which are permitted to receive greater than 20 tons of waste per operating day shallcomply with the new requirements by September 21,2008. On August 19,2008,the CIWMB proposed.to revise the regulations yet again,to extend the deadline for compliance with 27 CCR-20921 - Gas Monitoring and ControL The proposed revised regulations kept the -requirement to submit the Plans for active disposal sites that receive greater than 20 tons per day by September 21,2008. However,the proposed revised regulations also contain a provision that the landfill operators will not have to fully implement the Plans as approved by the EA and concurred with the GIWMB until eight months after the effective date of the proposed regulations or September 21,2009,whichever is later. 'The Plans for the Forward Landfill,Inc.were submitted to the LEA on September 16,2008. Because
